Honestly, if you ask the average person how many American bison are left, they’ll probably give you one of two answers. They’ll either say they’re basically extinct or that they’ve made this massive, triumphant comeback and everything is fine now.
Neither is really true.
The reality of the American bison in 2026 is a lot more complicated than a simple head count. It involves a strange mix of backyard hobbyists, massive commercial meat operations, and a relatively tiny handful of truly "wild" animals that still carry the DNA of their ancestors without a trace of domestic cattle mixed in.
The Current Head Count
So, let's get the big number out of the way first.
As of early 2026, there are roughly 500,000 to 650,000 bison in North America. That sounds like a lot, right? Especially when you consider that by the late 1880s, that number had plummeted from 30 million to just a few hundred individuals hiding out in the Yellowstone backcountry and a few private ranches.
But here is the catch.
About 90% to 95% of those half-million animals are actually livestock. They’re being raised on private ranches for meat. They are behind fences. They are often managed just like cattle, and in many cases, they actually have cattle DNA in their lineage from early 20th-century crossbreeding experiments.
Breaking Down the 2026 Populations
If you want to know how many "real" wild bison are left—the ones managed as wildlife—the number drops off a cliff.
- Conservation Herds: Roughly 30,000 bison are managed specifically for conservation by public agencies and non-profits like The Nature Conservancy.
- Truly Wild & Free-Roaming: Only about 5,000 bison are considered truly free-roaming and disease-free.
- Tribal Herds: Indigenous nations have led the most aggressive restoration efforts lately. Organizations like the InterTribal Buffalo Council now manage around 25,000 to 30,000 animals across 80+ tribes.
- Commercial Herds: The remaining 400,000+ live on private ranches.
Why the "Wildlife" Label Matters
You might think, Who cares if they're on a ranch or in a park? A bison is a bison. Well, not exactly. In most of the U.S., bison are legally classified as livestock. This means they don't have the same protections as elk or deer. If a bison wanders off a park's boundaries, it's often treated like a stray cow rather than a wild animal.
However, we are seeing some shifts. In April 2025, Colorado Governor Jared Polis signed the "Protect Wild Bison" bill, which finally designated bison as wildlife in that state. This is a big deal. It allows state wildlife agencies to manage them as a big game species and helps with the "ecologically extinct" problem.
The "Ecologically Extinct" Problem
Ecologists often use the term "ecologically extinct" when talking about bison. It means that while the animals exist, there aren't enough of them moving freely across the landscape to actually do their job.

Bison are "ecosystem engineers." They wallow in the dirt, creating depressions that hold rainwater for insects and amphibians. They graze in a patchy way that promotes wildflower growth. When they are stuck behind a 6-foot reinforced fence on a 100-acre ranch, the prairie doesn't get those benefits.
To truly restore the species, biologists at groups like American Prairie argue we need herds of at least 5,000 animals roaming across massive, unfenced landscapes. We aren't there yet.
The Genetic Ticking Time Bomb
Genetic diversity is the secret hurdle no one talks about. Because the entire species was rebuilt from a tiny handful of survivors, the gene pool is narrow.
Even worse, many of the "conservation" herds are tiny. We’re talking 20 or 50 animals in a fenced-in state park. Over time, this leads to inbreeding. In 2026, we’re seeing more "genetic swapping" programs where bulls are trucked from one park to another just to keep the bloodlines fresh.
And then there's the "cattle gene" issue. Most bison in America have a tiny bit of Bos taurus (domestic cow) DNA. Finding "pure" bison is surprisingly hard. Yellowstone National Park and Elk Island in Canada are two of the only places left with large, truly pure herds.
The Role of Native Tribes
If there's a reason to be optimistic about how many American bison are left, it's because of Tribal leadership.
Between 2012 and 2017, bison numbers on Native lands jumped by over 1,000%. That momentum hasn't stopped. For many tribes, this isn't just about biology; it’s about "cultural renewal." They are bringing the "Buffalo" (the term many tribes prefer over bison) back to the land to restore a spiritual and nutritional connection that was severed in the 19th century.
In Montana, the Fort Peck and Fort Belknap reservations have become critical hubs for receiving "surplus" bison from Yellowstone. Instead of those animals being sent to slaughter when they wander out of the park, they are now often relocated to Tribal lands to start new, genetically pure herds.
Modern Threats: It's Not Just Hunters Anymore
In the 1800s, the threat was a Sharps rifle. Today, it's a bit more subtle.
- Climate Change: A study mentioned by the Smithsonian noted that as the Great Plains get warmer, the grass contains less protein. Bison are actually shrinking in size because their "fuel" isn't as calorie-dense as it used to be.
- Winter Survival: In Alaska, the experimental Wood Bison restoration project hit a massive snag during the 2022-2023 winter. Deep snow froze into a layer of ice, and dozens of bison starved because they couldn't break through to the grass. In 2026, these "extreme weather events" are becoming the new bottleneck for population growth.
- Human Intolerance: People love the idea of bison, but they don't always love a 2,000-pound animal standing in the middle of a highway or breaking a fence to get into a hay field.
The 1 Million Goal
Back in 2017, the National Bison Association set a goal to have 1 million bison in North America by 2027.
Are we going to make it?
Probably not by next year. But we’re closer than we’ve been in 150 years. The growth is steady, but it's increasingly lopsided toward the commercial side. If you want to see a world where bison are truly "wild" again, the number to watch isn't the 500,000—it's the 30,000 in conservation herds.
How You Can Actually Help
If you're looking to support the return of the bison, your choices as a consumer and a citizen actually matter quite a bit.
Support Tribal-Led Restoration Look for organizations like the Tanka Fund or the InterTribal Buffalo Council. They are doing the heavy lifting of returning bison to large landscapes where they can live as wildlife.
Choose Your Meat Wisely If you eat bison, find out how it was raised. Regenerative ranches that allow bison to graze in large, diverse pastures are helping maintain the species' health, even if those animals are technically "livestock."

Advocate for Wildlife Status Keep an eye on state legislation. Following Colorado's lead, other states are debating whether to reclassify bison as wildlife. Supporting these measures helps remove the legal barriers that keep bison behind fences.
Visit the Big Herds Go to places like Theodore Roosevelt National Park, the Badlands, or the American Prairie in Montana. Tourism dollars in these areas prove to local governments that live bison are worth more than the trouble they might cause.
The American bison isn't going extinct again. That battle has been won. The new battle is making sure they aren't just "flat-screen wildlife"—something we only see in small, controlled doses—but a living, breathing part of the American landscape.
